Star Ocean and End of Eternity developer tri-Ace is currently working on Frontier Gate for PSP and Beyond the Labyrinth for 3DS. But it turns out that in addition to these portable projects, the studio was contributing to development of another major project.

tri-Ace producer Yichiro Kitao, who worked on the programming aspects of End of Eternity (Resonance of Fate), the Valkyrie Profile series, and Star Ocean 3, revealed today at Twitter that the studio took part in the development of Final Fantasy XIII-2. Square Enix enlisted tri-Ace's help for game design, artwork, programming, and other areas of the game.
